Yamaha Owners ?

i have a vmax 200 ox66 3.1 L and my oil alarm went of during a tourny 2 weeks ago. i had nearly 2 gallons in the tank on the boat, and when i got home the oil was between the 2 arrows in the tank on the engine. i was told to turn the key on and hold the toggle switch on the engine and if the oil fills the tank up, itis NOT the oil pump on tthe tank in the boat. i was told it was the sensor inside the tank on the engine. i replaced the sensor($135) and when i went out last week the alarm never sounded, but the arrow on my tach never went to green. it stayed on yellow indicating that i was getting low. when i got home and popped the cowling, i could tell the oil had gone down some, but now im confused. what can i check next before i lose my mind? please help.

Who told you it was the sensor?  There are times, and this may be one of them, when it's best to have someone with the electronic testing equipment, and the training, do the job.  There are times that the aggravation and frustration are not a fair trade off to save a few bucks.  That's particularly so when you are dealing with a critical component such as the one that's giving you grief.

 

I used to enjoy working on my cars.  That ended when computers, chips, engine control modules and a gazillion sensors took over control of the drive train functions.  Yesterday was a perfect example.  I was checking out a new, to me, place with an unimproved ramp.  I got into some soft sand and put my truck in four wheel drive.  I decided not to launch and when I got back onto the road, my truck would not shift out of four wheel drive.  Got a "have four wheel drive serviced" message on the info display.

 

Off to the dealer where I have my truck serviced.

 

When they connected the diagnostic computer to my truck, it turned out that the tranny/transfer case could not complete the shift.  It was a software issue.  The control module needed an update (or upgrade, forget which).

You got to remember when you jump into the big 2 stroke engines, oil use is usually about 50/1 meaning if you go 50 miles you

should use about 1 gallon of oil.  100 miles you will go through 2 gallons.  Not only is gasoline expensive on big outboards, but

the consumption of oils is another reason big motor owners start to thing four stroke.  Most big motors will average about 2 mpg,

while the four strokers avg around 8 mpg.  Just something to keep under your hat.

There's something wrong with that math.  50/1 is the gas to oil mixture, not that you'll get fifty miles out of one gallon of oil.  If that were the case, it would mean that to burn a gallon of oil, he'd have to burn fifty gallons of gasoline.  I don't think it will take 51 gallons of fuel/oil mix to go fifty miles.

The gentlemen I bought my boat from had his oil injection go out and smoke his motor. Now he only uses premix. I too do this as well per his advice. It is the only sure fire way to know exactly what you are getting. I mix 4 ones per gallon. I carry a measuring cup in my boat. When I put gas in my boat I put in the appropriate amount of oil and sta bil.

You are correct it is more like a hundred miles, seeing as 2 strokes generally get 2 mpg.
